Abstract:
The present invention is related to a composition of PI3K inhibitor, comprising: 0.01˜10 mg of PI3K inhibitor; 10˜500 mg of poly(lactic-co-glycolic acid) (PLGA) which is encapsulated onto the surface of the PI3K inhibitor and the surface is non-modified by a modifier; and the composition has a size of 10˜1000 nm. Thereby, an excellent effect on suppressing the growth of tumor cells will be achieved by the encapsulation of PI3K inhibitor into PLGA nanomaterials without any modifier on its surface, the optimization of a ratio of PI3K inhibitor to PLGA, and the accordingly slow release of the composition.
Abstract:
A nucleic acid cleavage kit is used to cleave a target nucleic acid. The nucleic acid cleavage kit includes a carrier, an oligonucleotide, and a nucleic acid cleavage agent. The oligonucleotide recognizes at least partial sequence of the target nucleic acid. Then, the nucleic acid cleavage agent cleaves the target nucleic acid. A nucleic acid cleavage detection apparatus including the nucleic acid cleaving kit and a gene therapy by administering the nucleic acid cleavage kit are also disclosed.
Abstract:
An optical detection apparatus used for detecting a tissue includes a light-emitting unit, a spectroscopic unit and a light-sensing array. The light-emitting unit emits light entering into the tissue. The spectroscopic unit receives the light outputted from the tissue and divides the received light into a plurality of rays with different wavelengths. The light-sensing array senses the rays outputted from the spectroscopic unit so as to generate an array spectrum. By the spectroscopic unit, the detection of the rays of multiple wavelengths can be performed without using plural light-emitting diodes for emitting light of different wavelengths. Besides, the user can perceive the detection result (e.g. the location of the abnormal tissue) intuitively by integrating the light-sensing array and the spectroscopic unit.

Abstract:
The present invention relates to a process for preparing water-soluble and dispersed iron oxide (Fe3O4) nanoparticles and application thereof, characterized in which two-stage additions of protective agent and chemical co-precipitation are employed in the process. In the first stage, Fe3O4 nanoparticles are obtained using absorbent-reactant coexistence technology. In the second stage, proper amount of adherent is added to cover the nanoparticle surface entirely. The resulting water-soluble and dispersed Fe3O4 nanoparticles can easily bind with thiols or biomolecules, such as nucleic acid and peptide. The Fe3O4 nanoparticles of the present invention may be used as magnetic resonance imaging contrast agent and used in magnetic guiding related biomolecular technologies for clinical testing, diagnosis and treatment.
